Heater



Patented July 14, 1931 LAWRENCE ELMER REILEY, 0F GOLDETIELD, NEVADA HEATER i Application led April 27,

My invention relates to improvements in heaters, and it consists in the combinations, constructions and arrangements hereinafter described and claimed.

An object of my invention is to provide a heater in which air from the combustion chamber can be directed into a chimney by opening a damper in the chimney, or can be sent through a circuitous path through a number of lines before being discharged into the chimney. Hot air pipes are disposed adjacent to the pipes bearing the heated gases, and heat is transferred from the gases to the air passing through the pipes. During a portion of the path ofthe heated gases, they are directed downwardly so as to give off the greater part of their heat.

A further object of my invention is to provide a device of the type described which is' extremely 4simple in construction and which is durable and eiiicient for the purpose intended.

Other objects and advantages will appear as the specilication proceeds, and the novel features will be particularly pointed out in the appended claims.

My invention is illustrated in the accompanying drawings, in which Figure 1 is a perspective view of the device;

Figure 2 is a section along the line 2-2 of Figure 1; and

Figure 3 is a section along the line 3-3 of Figure 1.

In carrying out my invention I provide a base 1 that is supported by legs 2. The base carries an ash pit 3 and a. combustion chamber 4 disposed above the ash pit. A U-shaped passageway 5 encloses the two sides and back of the ash pit. An ash door 6 is disposed at the front of the heater as shown in Figure 1. This door carries a controlled vent by means of which the air entering the combustion chamber 4 may be regulated.

A plurality of vertically-extending heatconveying pipes 8 are disposed on the two sides of the combustion chamber. Figures 1 and 2 show these pipes 8 as opening into the top of the combustion chamber as at 9 and into the U-shaped passageway 5 as at 10.

1929. serial No. 358,689.

Air-heatingpipes 11 are disposed between the pipes 8 and have an opening 12 in their bottoms (see Figure`2) and an opening `13 intheir tops. Air enters through the opening 12 as shown by the broken line w in Figure 2 and passes onthrough thepipe 11 and out the opening 13. The air is heated as it passes through the pipe. Additional' air f pipes 11 are disposed at the back of the heater and on either side of a fiue 14.

The combustion chamber 4 has a door 15 (see Figure 1) for receiving `fuel. In the upper back wall 16 of the combustion chamber 14 I mount a damper 17. This damper is movable into closed or open position by i means oi a handle 18 (see Figure 3). At the bottom of the flue 14 I dispose a door 19 which may be opened for cleaning out the flue'and the rear portion of the passageway 5.

From the foregoing description of the va- L rious parts of the device, the operation thereof maybe readily understood.

Thek damper 17 is kept in open position until the fire within the combustion chamber 4 gets well started. The closing oi the damper will cause the heated air to pass through the openings 9 in the top of the combustion chamber 4 andthen to flow downwardly through the pipes 8 and into the Ueshaped member 5. Here the gases will flow to the back of the U- shaped member and then up the flue 14. During all of this movement, the heat is be'- ing transferred from the flue gases to the air flowing through the pipes 11. This air is kept circulating inthe room and quickly heats it.

It will be seen from Figure 2'that the pipes 8 and 11 are formed from the same casting that makes up the combustion chamber or fire boX 4. In this way the pipes 8 and 11 will be heated by the fire in the tire box, and the heat will then flow through the pipes 8 and will cause these to give off additional heat. The door 15 hasaJ sliding vent 15 that may be moved or controlling the amount of air enifsering the combustion chamber 4 above the Figures 1 and 3 show the openings 9 as being of different sizes, the smallest being positioned adjacent to the rear ot the fire box 4.

The openings are graduated in size. This will prevent the greater amount of heat from passing up through the rearmost pipes 8, but instead will cause a more uniform distribution of heat throughout all of the pipes.

The air flowing through the pipes 11 is warmed by the heat given oli' by the pipes 8 and also by the walls of the combustion chamber 4. The heat flowing through the iue or chimney 14 also heats the air in theppipes V1l disposed adjacent. thereto.` that the heater does radiate heat as well as heating the air flowing through the pipes 11.

The parts of the heater are arranged so that the)7 may be readily assembled or disassembled.

Although I have shown and described one embodimentI of my invention, it is to be understood that the same is susceptible of various changes, and I reserve the right to employ such changes as may come within the scope of the invention as claimed.

I claim:

l. A heater comprising a lire box, an outlet liuc, a plurality of vertical passageways for th-e products of combustion leading from the top of the tire box to the bottom thereof, and a horizontal passageway connecting the bottoms of the first named passageways with the liuc, the entrance openings of the vertical passageways being smallest for the ones disposed nearest the back of the irebox and increasing in size for. the ones disposed near the front, whereby a uniform flow of h-eat will pass through all of the passageways.

2. A heater comprising a fire box, a U- shaped conduit disposed at the bottom of the heater, conduits leading from the top of the lire box to the U-shaped conduit, and air conveying conduits disposed between the first set of conduits and alternating therewith, said air conduits having their lower ends spaced above the U-shaped conduit and having their upper ends opening into the atmosphere, said first named conduits having entrance openings from the lire box thatare small for the conduits disposed near the back of the lire box and increasing in size for those disposed near the front of the -irebox LAVRENCE ELMER REILEY.
